You're searching for a studio, and suddenly you're scrolling through a list of options: 3D, 4D, 5D, HD, even "8K."
It sounds more like you're buying a new TV than booking an ultrasound. What's the real difference, and what do you really need to see your baby?
Let's break it down simply.
3D Ultrasound: Think of this as a still photograph. The machine scans from different angles to build one single, three-dimensional image. This is perfect for those frame-worthy pictures of your baby's face.
4D Ultrasound: This is a movie. The "4th dimension" is Time. You are seeing your baby's 3D image in real-time, live motion. This is how you catch them yawning, sucking their thumb, or waving 'hello.'
5D / HD / "8K": Think of these as a realistic enhancement. These are all marketing terms for advanced software that takes your 4D (movie) scan and adds a more lifelike, virtual light source. It smooths out the skin tone and adds shadows to make your baby look incredibly realistic and "fleshy."
So, what's the best choice?
Most keepsake studios today offer 4D, which is the experience everyone loves. The 5D/HD/8K options are like a premium "portrait mode" for your scan—an amazing add-on if you want the most stunning, true-to-life images possible.
